Have tu ever had a crush on someone but wish tu didn't?

tu know that feeling like tu know nothing is ever going to happen because tu know for a fact that they don't like tu the same way? If you've ever had this feeling and gotten rid of it how did tu do it? Cause honestly I'm falling for this guy and I really wish I wasn't cause he's not my type for one thing and I can tell for a fact nothing will ever happen. I also don't even want to be thinking about a relationship right now when I'm focusing on me only. I'm frustrated and I just want to strangle someone.. :(
